Specification of Letters Patent.

Application led November 9, 1909. Serial No. 526,949.

Patented Mar.4,1913.

To all 'whom 'it may concern# Be it known thatl I, ADoLr` P. LINK, a citizen of the United States, and a resident of the cit of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Boiler, of which the following is a full, clear, and exact description. My invention relates to boilers, my purpose being to improve the general efficiency of apparatus of this kind; the object of the invention being to facilitate the capture and removal of mud or other lresiduum from within a boiler. v

Reference is to be had to the accompanying drawings forming `a part of this specification, in which similar characters of reference indicate corresponding parts in the igures.

Figure 1 is a view partly in side elevation and partl in section, showing the apparatus; and i 2 is a horizontal sect-ion on the 1ine'2-2 o Fig. 1, looking in the direction of the arrow.

The boiler 6 comprises a pot 12 provided with a rounded rim 13, and mounted .within the pot adjacent to this rim is a flange 14.y

A top 15 is provided for this pot and has generally the form ofa frusto-conical dome, the loweI` edge of this top fitting between the flange 14 and the upper edge of the pot, and thereby forming a substantially airtight lit. Disposed centrally within the pot 12 is a pipe 16 having generally a frustoconical shape and provided at its bottom with a flange 17, the ed e of this flange being provided with corgations 18. The pot 12 is provided with screens 121 and 12", as shown 1n Fig. 1.

The pipe 16 is provided with a cylindrical portion 20 extending upwardly. pan'` 22 1s provided centrally wlth a cylindrical po'rtion 21 which fits over the cylindrical portion 20 so that the pan is supported firmly in position. This pan,jbecause of its use, I designate as the mud pan. It is employed to receive the mud thrown up during the operation of boiling, as hereinafter described. V l

Mounted in the upper portion of the m'ud pan 22 is an annular screen 23 made preferably of sheet metal provided with openings. Above 'this screen is another screen 24 made preferably of woven wire. The inner edge of the screen last mentioned is bent downwardly, as indicated in(Fig. 1, so as to' engage the adjacent inner edge of the screen 23. A deflecting hood 25, having substantially the form of a bell, encircles the cylindrical portion 20 and rests directly upon the cylindrical portion 21.

A dome 26 is, by aid of a spider 27, mounted u on the upper end of the cylindrical mem er 20 in such manner as not to obstruct this member. The lower end of this spider 27 is provided with a collar 28 which ts directly upon the upper or neck portion of the -hood 25.

A liquid 16" is placed within the boiler and heat is applied in the usual manner. If the liquid contains any mud or other impurities of a residual character, they are removed first by overboiling; the heavier impurities, for Vinst-ance, substances such as mud, often tend to settle near the bottom of a boiler and to become gradually hardened and form a scale unless they are removed. I therefore seek to remove them at an early stage, and more particularly as b so doing the bottom part of the boiler an parts adjacent to the same are kept clean and are thus rendered comparatively easy to heat.

The vapor arising 4from the liquid passes upwardly through the screens 12, 12", and out through the dome 15.' Any mud or residuum which may tend to collect in the bottom of the boiler is carried upwardly through the pipe 16 and passes out of the upper end of the cylindrical portion `20 into the dome 26., 4It cannot travel any higher than this and'is turned back, along with any water which will be carried with it, droppin upon the hood 25 and falling into the mud pan. At intervals this mud or other solid residuum is removed. 'l In order to do this, the top 15 is first taken oil', the screen 12b is lifted out, the dome'26 and hood 25 are next taken off, and finally the mud pan is removed and the mud, or other residuum is rejected from it. The parts are replaced in inverse order. While the 'mud thus tends to ascend through the conical pipe 16, this does not prevent the formation of vapor in the body of the liquid 16, and this lvapor finds its way upwardly and passes through the screens 12, 12", into the top 15.- This 4water of condensation, and also for preventing the overflow ofthe liquid upon the outside. The metal screens 12a, 23 break up the bubbles and the fine woven screens prevent excessive foaming and overboiling.

. The mud pan 22 is provided with small radially disposed holes, one of which is sho n at 22, for allowing any water of con ensation which may happen to get intok the pan, to flow out into the boiler 12. Any water which may at any time be contained in the mud pan 22, therefore, has a higher level than that of the liquid 16 in the loo-iler. The metal screens 12a, 23 have unobstructed evaporating space, in order to facilitate-vaporization and to prevent undue condensa' The upper edge 32 ofi-the collar 30 bears away slightly from the upper edge of the neck -29 ,sov as to leave an annular space.

. Fitting into this annular space is the lower end of a vapor pipe 33 for conducting. the vapor from the boiler. A pipe 61`is connected with the lowerv portion of the boiler to supply the same with water, the pipe being connected with a suit-able supply for mainy -tainingthe level of the liquid in the boiler.
